The transparency of a texture map, also known as the Alpha channel, is an important parameter that controls how transparent or opaque a texture is. By editing transparency, you can create various visual effects, such as semi-transparent glass, delicate water surfaces, and even complex materials like fabrics or hair. In this article, we will delve into how to edit the transparency of texture maps and introduce several common methods and tools for achieving this.
<img style="display: block; margin-left: auto; margin-right: auto;" src="https://img.relebook.com/news/edit/2024-11-14/a8425812-66dc-4500-a975-fa3589049bcd.png" alt="How to Edit the Transparency of Texture Maps" width="700" height="405">
<h2>Basics of Texture Maps and Transparency</h2>
Texture maps are essentially image files that are mapped onto the surface of 3D models to add color, detail, and texture. A texture map can include several channels, typically including color channels (RGB) and the Alpha channel (transparency). The Alpha channel defines the transparency level of a texture, determining which areas are fully transparent, partially transparent, or fully opaque.
In 3D rendering, transparency is typically achieved using a grayscale image (Alpha map), where the lower the Alpha value, the more transparent it is, and the higher the value, the more opaque it becomes. For example, a white Alpha map represents full opacity, a black Alpha map represents full transparency, and gray represents partial transparency. By editing the Alpha channel, artists can control the transparency of textures, thus achieving various visual effects.

In 3D game development, the surface details of characters, environments, and props largely depend on the textures applied to them. Textures not only provide color, gloss, and surface details, but they also play a crucial role in enhancing visual effects and immersion. Whether you're working on character modeling, scene design, or prop creation, the right textures can significantly elevate the quality of the project. Commonly used 3D software such as Blender, 3ds Max, and Maya all offer powerful tools for texture creation and application. This article will explore how to create textures for 3D games, introducing key techniques and methods.
<img src="https://img.relebook.com/news/edit/2024-11-13/97b78580-89b9-49ef-a164-40a784d9fd7c.png"> 1. Choose the Right Type of Texture Different game projects require different types of textures, so it&rsquo;s essential to choose the right one based on the needs of the project. Common types of textures include base textures, normal maps, roughness maps, and reflection maps. Base Texture Base textures provide color, detail, and surface characteristics for models. These can include things like character skin, clothing, building walls, and ground textures such as grass. When designing base textures, it's important to consider the material's properties, such as wood, stone, metal, or fabric. Normal Maps Normal maps simulate surface detail, like bumps and grooves, without adding extra geometry. By adjusting the direction of surface normals, normal maps give objects realistic lighting effects, creating the illusion of depth. Roughness and Reflection Maps Roughness maps control the surface&rsquo;s glossiness and detail, simulating how light interacts with different materials. Reflection maps are used to simulate mirror-like reflections, such as those found on metal surfaces or water. 2. Use High-Quality Texture Resources When creating textures for games, using high-quality texture resources can save time and significantly improve the game's visual appeal. Many websites and platforms offer extensive texture libraries, allowing designers to find resources that suit the project&rsquo;s needs. Online Texture Libraries Platforms like Texture Haven, Polyhaven, and Relebook provide both free and paid texture resources. These platforms offer textures for various materials, from common surfaces like floors and walls to specialized textures for metal, glass, and more. Designers can quickly download and apply them. Custom Textures In addition to using pre-made textures, designers can also create custom textures by painting or adjusting them as needed. Tools like Substance Painter allow designers to paint directly onto 3D models, while Photoshop can be used to tweak images and create unique effects. 3. Create Textures for Different Materials Different materials require different techniques when it comes to texture creation. Depending on the material type, textures need to account for properties like reflection, refraction, transparency, and roughness. Metal Textures Metal surfaces are typically highly reflective, so it&rsquo;s important to focus on reflection maps and roughness maps. Designers can control the glossiness of metals by adjusting roughness, and use specular highlights and reflections to define details. Organic Textures Textures for organic materials, such as skin, fabric, or wood, require fine detail. Designers can use high-resolution maps and detail textures to simulate things like skin pores, wrinkles, and textures found in natural materials, or manually paint them for a more organic look. Transparent Materials and Glass For transparent materials like glass, liquids, or water surfaces, textures must account for transparency, reflection, and refraction effects. In 3D software, designers can use refraction and reflection maps to simulate the optical properties of these materials.
<img src="https://img.relebook.com/news/edit/2024-11-13/9b3db316-ef4a-4adc-b190-d0cbe83f5adc.png"> 4. UV Unwrapping and Texture Mapping Accurate texture application relies heavily on UV unwrapping. UV unwrapping is the process of "flattening" a 3D model's surface into a 2D plane, which makes it easier to apply textures accurately. Proper UV mapping ensures seamless texture application, preventing stretching or distortion. UV Unwrapping Techniques In software like Blender or 3ds Max, designers can use automatic or manual UV unwrapping tools. For complex models, manually adjusting UV seams, optimizing splits, and fixing seams can help prevent noticeable stretching or mismatched textures. Seamless Texture Stitching Seamless texture stitching is key to high-quality texture creation. Designers need to pay attention to how textures tile across UV layouts, ensuring that there are no unnatural seams or color mismatches. 5. Use Proper Rendering Settings The effect of textures isn&rsquo;t only dependent on the textures themselves, but also on the rendering settings. Different lighting conditions and render engines can impact the final look of textures, so it&rsquo;s essential to adjust settings based on the specific project. Lighting and Reflection During rendering, designers need to adjust lighting, reflections, and shadow parameters to ensure textures look natural under various lighting conditions. For instance, using HDR lighting maps can simulate complex environmental lighting, adding realism to scenes. Render Engine Selection Different rendering engines, such as V-Ray, Cycles, or Unreal Engine, can affect how textures are rendered. Designers should select the appropriate render engine based on project requirements, and adjust materials and texture settings according to the engine's capabilities. Creating textures for 3D games is a multi-faceted process that involves various skills, from choosing the right texture types and using high-quality resources to carefully unwrapping UVs and adjusting rendering settings. Mastering these techniques will help designers create more immersive and realistic game scenes and characters. Hopefully, this article has provided useful insights into the texture creation process and can help you improve your design skills. If you're looking for high-quality 3D texture resources, SketchUp models, or 3ds Max models to create detailed models and virtual environments, Relebook offers a wealth of options that can help bring your project&rsquo;s visuals to the next level.

When using Rhino for 3D modeling and other related operations, we sometimes add various texture maps to models to enrich their appearance. However, in some cases, we may need to delete these added texture maps, such as when we want to replace them with new ones, simplify the model's appearance, or correct errors in the application of texture maps. This article will explain in detail the specific methods for deleting texture maps in Rhino to help you easily handle this operational requirement.
<img style="display: block; margin-left: auto; margin-right: auto;" src="https://img.relebook.com/news/edit/2024-11-13/dcf77819-cced-4566-811c-21654dcff907.png" alt="How to Delete Texture Maps in Rhino" width="700" height="405">
<h2>Understanding the Basic Concept of Texture Maps in Rhino</h2>
Before delving into how to delete texture maps, let's first briefly understand what texture maps are in Rhino. A texture map is essentially mapping a two-dimensional image onto the surface of a three-dimensional model, thereby making the model appear more realistic and have a richer visual effect. For example, we can apply a wood grain texture map to a simple cube model, making it look like a real wooden block. In Rhino, texture maps are associated with models through a series of settings and operations. And when we want to delete them, we also need to follow specific steps.
<h2>Deleting Texture Maps Directly in the Material Editor</h2>
1. Opening the Material Editor
First, we need to find and open the material editor in Rhino. Usually, in the Rhino interface, there are specific menu options or tool buttons to access the material editor. For example, in some versions of Rhino, we can find the relevant entry in the "Properties" panel or the "Tools" menu bar. After entering the material editor, we can see the various materials applied to the current model and their related settings.
2. Locating the Material with the Texture Map
In the material editor, all the materials applied to the model will be listed. We need to carefully examine these materials to find the one with the texture map we want to delete. This may require us to make judgments based on the model's appearance and our memory of previous mapping operations. For example, if we previously applied a stone texture map to a certain face of the model, we can find the corresponding material by observing the preview effect or the name of the material.
3. The Specific Operation of Deleting the Texture Map
Once we have identified the material with the target texture map, the next step is the key operation of deleting the texture map. In the setting area of this material, there is usually a section dedicated to managing texture maps. Here, we can see the relevant information of the currently applied texture map, such as the path of the map, the preview image, etc. After finding the corresponding texture map, there is usually a button like "Delete", "Remove", or "Clear" (the specific wording may vary depending on the version). Clicking this button will delete the texture map from this material.
<img style="display: block; margin-left: auto; margin-right: auto;" src="https://img.relebook.com/news/edit/2024-11-13/0d8e09bd-b3e5-4def-98d1-0b37e8fa12a5.png" alt="How to Delete Texture Maps in Rhino" width="700" height="405">
<h2>Deleting Texture Maps Through the Object Properties Panel</h2>
1. Selecting the Object with the Texture Map
To delete texture maps through the object properties panel, the first step is, of course, to select the object with the texture map we want to delete. In the Rhino view window, we can directly click to select the object with the mouse, or we can use some selection tools, such as the box selection tool or the cross selection tool, to accurately select the target object.
2. Opening the Object Properties Panel
After selecting the object, we need to open the object's properties panel. In Rhino, there are also multiple ways to open the object properties panel. Commonly, we can right-click on the selected object and then choose the "Properties" option in the pop-up menu to open the object properties panel. In this panel, we can see various property information about the object, including the materials it applies the texture maps, etc.
3. The Operation of Deleting the Texture Map
In the object properties panel, find the relevant setting area for materials and texture maps. Here, the materials applied to the current object and the texture map situation under this material will be shown. Similar to the material editor, we can see some basic information on the texture map and related operation buttons. After finding the corresponding texture map, click the button like "Delete" or "Remove" (the specific wording may be different), and the texture map can be deleted from this object.
<h2>Deleting Texture Maps Using the Command Line</h2>
1. Bringing up the Command Line Window
The command-line window in Rhino is a very powerful tool, and we can execute many operations through it, including deleting texture maps. To bring up the command-line window, usually we can find the corresponding menu option or shortcut key in the Rhino interface. For example, in some versions, we can bring up the command line window by pressing the "Ctrl + F1" combination key.
2. Entering the Command to Delete the Texture Map
After the command-line window appears, we need to enter a specific command to delete the texture map. Different versions of Rhino may have slightly different commands, but generally, common commands for deleting texture maps are similar to "-RemoveTexture" or "-DeleteTexture" (these are just examples, and the actual command depends on the specific version). After entering the correct command, press the Enter key.
3. Specifying the Object or Material from Which to Delete the Texture Map
After pressing the Enter key, the system will prompt us to specify the object or material from which to delete the texture map. At this time, we need to follow the prompt, select the object from which to delete the texture map in the view window with the mouse, or select the corresponding material in the material editor. After the selection is completed, press the Enter key again to complete the deletion operation of the texture map.
Through the above introduction of the multiple methods for deleting texture maps in Rhino and the answers to some common questions, I believe that when you are faced with the task of deleting texture maps from Rhino models, you already have a relatively clear idea and operational method. I hope these contents can help you better manage and operate texture maps in Rhino. If you want to obtain more high-quality 3D models and textures, you can download them from the Relebook website. Abundant resources are waiting for you to explore.
<h2>FAQ</h2>
What Should I Do If the Model's Appearance Doesn't Change After Deleting the Texture Map?
Sometimes, after deleting the texture map, we find that the model's appearance doesn't change as expected. This may be because there are other settings affecting the appearance of the model, such as the color, glossiness, etc. of the material. We can enter the material editor or the object properties panel again, and check and adjust these related properties to make the model's appearance return to the state we want.
What Should I Do If I Accidentally Delete the Wrong Texture Map?
If you accidentally delete the wrong texture map, don't panic. If you have previously saved a file version with the correct texture map, you can reopen that file and restore it to the previous state. Or, if you know where the original texture map was obtained from, you can reapply that texture map to the model, following the steps of adding it before.
What Should I Do If I Can't Find the Texture Map to Be Deleted in the Material Editor?
If you can't find the texture map to be deleted in the material editor, it may be because the material settings are complex or you haven't correctly located the material with the texture map. At this time, you can try to find and delete the texture map through the object properties panel, following the method of deleting texture maps through the object properties panel introduced above.

How to Delete Texture Maps in Rhino?

In the field of 3D modeling and animation production, UV mapping is a crucial technical aspect. It enables the accurate mapping of 2D textures onto the surface of 3D models, thereby allowing the models to present more realistic and rich visual effects. Whether it's creating realistic game scenes, producing wonderful animated films, or conducting virtual presentations of various products, etc., reasonable and precise UV mapping operations are indispensable. The sphere, as a common basic geometric shape, appears frequently in many projects. Mastering how to do UV mapping on a sphere in Maya lays an important foundation for subsequent more complex model UV processing. This article will elaborate on the specific methods and related key points of doing UV mapping on a sphere in the Maya software.
<img style="display: block; margin-left: auto; margin-right: auto;" src="https://img.relebook.com/news/edit/2024-11-12/f20833dc-bd41-4386-bc1b-9fb110c7b329.png" alt="How to Do UV Mapping on a Sphere in Maya" width="700" height="405">
<h2>Overview of Maya Software and UV Mapping Basics</h2>
1. Introduction to Maya Software
Maya is a powerful 3D modeling, animation, and rendering software widely used in fields such as film and television, games, and animation. It has a rich and diverse set of tools that can meet a series of needs, from creating basic geometric models to producing complex character animations. Its interface design is relatively intuitive, but for beginners, the numerous functional modules may still take some time to get familiar with and master.
2. Understanding the Concept of UV Mapping
UV mapping is actually about establishing a correspondence relationship between the surface of a 3D model and a 2D texture. We can imagine the 3D model as an object that needs to be packaged, and the 2D texture is the piece of paper used to wrap it. The UV coordinates are the keys to determining how accurately this "paper" wraps around the object. Here, U and V represent the horizontal and vertical coordinates, respectively. By reasonably adjusting the UV coordinates, we can make the texture distribute ideally on the surface of the model.
<img style="display: block; margin-left: auto; margin-right: auto;" src="https://img.relebook.com/news/edit/2024-11-12/e00f6342-6f97-4c59-917b-a76dcd353b18.png" alt="How to Do UV Mapping on a Sphere in Maya" width="700" height="405">
<h2>Creating a Sphere Model</h2>
Before doing UV mapping, we first need to create a sphere model in Maya. The operation steps are as follows:
1. Open the Maya software and enter its main interface.
2. Select the "Create" option in the menu bar, and then find "Polygon Primitives" in the drop-down menu.
3. Click "Sphere" from the sub-menu of "Polygon Primitives," and a sphere model with default parameters will appear in the scene view.
Of course, we can also adjust the parameters of the sphere according to specific requirements, such as the radius size and the number of subdivision segments. Different settings of these parameters will have a certain impact on the effect of subsequent UV mapping. Generally speaking, the higher the number of subdivision segments, the smoother the surface of the model will be, and a more refined effect can be obtained when doing UV mapping, but it will also increase the amount of calculation and the complexity of the operation.
<h2>Entering the UV Editing Mode</h2>
After the sphere model is created, the next step is to enter the UV editing mode to perform relevant operations on the UV of the sphere. The specific steps are as follows:
1. Select the newly created sphere model in the scene view. This can be achieved by clicking the sphere with the left mouse button.
2. Then find the "UV" option in the menu bar and click it.
3. Select "UV Editor" from the drop-down menu of "UV," and the UV Editor window will pop up. In this window, we can see the initial UV layout corresponding to the sphere model.
The initial UV layout may not be the final effect we want. It is often relatively simple and may have some unreasonable aspects, such as texture stretching and distortion problems. This requires us to optimize and adjust it through a series of subsequent operations.
<h2>Automatic UV Unfolding</h2>
Maya provides the function of automatic UV unfolding, which is a relatively convenient and fast way for beginners or in cases where the precision requirement of UV is not particularly high. The operation steps are as follows:
1. In the UV editor window, make sure the UV of the sphere is selected. If it is not selected, you can click the UV of the sphere in the UV layout area with the mouse to select it.
2. Then find the "Polygons" option in the menu bar of the UV editor window and click it.
3. Select "Automatic Mapping" from the drop-down menu of "Polygons," and Maya will perform the automatic UV unfolding operation on the sphere according to its algorithm.
The UV layout after automatic unfolding will be relatively regular, but there may still be some small problems, such as slight texture stretching or unnatural splicing in some areas. At this time, we need to further manually adjust the UV to achieve a more perfect effect.
<h2>Manual UV Adjustment</h2>
Manual UV adjustment is the key step to obtaining a high-quality UV mapping effect. Although it is relatively time-consuming, it enables fine control of the UV layout. The following are some common methods of manual UV adjustment:
1. Moving UV Vertices
In the UV editor window, you can directly drag the position of UV vertices with the mouse to change the UV layout. For example, if you find that the texture in a certain area is stretched, you can try to move the UV vertices corresponding to that area in the appropriate direction to relieve the stretching situation. When operating, pay attention to observing the changes of the texture on the surface of the model to ensure that the UV layout after moving can make the texture distribute evenly and naturally on the surface of the sphere.
2. Cutting UV Edges
Sometimes, to better adjust the UV layout, it is necessary to cut UV edges. In the UV editor window, select the "Edit UVs" option, and then find "Cut UVs" in the drop-down menu. Then click the UV edge that needs to be cut with the mouse, and it can be cut off. The cut UV edges can be moved, rotated, etc. separately to better optimize the UV layout. However, pay attention to choosing a reasonable cutting position to avoid excessive cutting that may make the UV layout too fragmented and affect the mapping effect of subsequent textures.
3. Stitching UV Edges
After cutting UV edges, it may be necessary to stitch some of the cut UV edges back together to restore the integrity of the UV layout. In the UV editor window, select the "Edit UVs" option, and then find "Stitching UV Edges" in the drop-down menu. Click the endpoints of the UV edges that need to be stitched one by one with the mouse, and they can be stitched together. During the stitching process, pay attention to ensuring that the stitched UV edges can match accurately to avoid texture misalignment and other problems.
Through the above methods of manual UV adjustment, the UV layout of the sphere can be finely optimized, so that the texture can present a more ideal effect on the surface of the sphere.
<h2>Adding Textures</h2>
When the UV layout of the sphere is adjusted to a satisfactory level, we can add textures to the sphere. The specific steps are as follows:
1. In the main interface of Maya, find the "Hypershade" (material editor) window. You can open it by selecting the "Window" option in the menu bar and then finding "Hypershade" in the drop-down menu.
2. In the "Hypershade" window, create a new material node. For example, you can create a "Lambert" material node, which is a commonly used basic material.
3. Connect the created material node to the sphere model. You can do this by dragging the material node from the "Hypershade" window to the sphere model with the middle mouse button to establish a connection.
4. Then, add a texture to the material node. You can find the "Color" (color) property in the property editor of the material node and then click the "Create" (create) button next to it. In the pop-up menu, select the appropriate texture type, such as "File" (file) texture, and then select the corresponding texture file to load it onto the material node.
In this way, after the previous series of UV mapping operations, the sphere model with the loaded texture will present an appearance with a real texture effect.

<h2>FAQ</h2>
Why is there still texture stretching in some areas of the sphere after automatic UV unfolding?
Answer: Although automatic UV unfolding is convenient and fast, it only operates according to the software's algorithm and may not fully consider the specific situation of the model. The shape of the sphere is rather special, and some areas may not get the optimal UV layout during the automatic unfolding process, thus resulting in texture stretching. At this time, it is necessary to manually adjust the UV by moving UV vertices, cutting and stitching UV edges, etc., to further optimize the UV layout and relieve the texture stretching problem.
What are the effects of cutting too many UV edges when manually adjusting UV?
Answer: Cutting too many UV edges will make the UV layout too fragmented, which may lead to unnatural texture splicing, misalignment, and other problems when loading textures later. Moreover, too many cuts will also increase the complexity of the operation and are not conducive to the overall grasp and optimization of the UV layout. Therefore, when cutting UV edges, choose the cutting position carefully and try to avoid excessive cutting.
What should I do if I can't find a suitable texture file when adding textures?
Answer: If you can't find a suitable texture file, you can consider making your textures. For example, you can use image processing software such as Adobe Photoshop to draw or synthesize the required textures. Additionally, you can also search and download some professional texture resource websites, such as textures.relebook.com, which provide a large number of rich and diverse texture resources for users to choose from.

In the field of 3D modeling and animation production, UV mapping is a crucial technical aspect. It enables the accurate mapping of 2D textures onto the surface of 3D models, thereby allowing the models to present more realistic and rich visual effects. Whe

How to Do UV Mapping on a Sphere in Maya?

In the world of 3D modeling and rendering, UV mapping is a crucial technique. It's like dressing a 3D model in a carefully customized "outfit", capable of endowing the model with rich details and a lifelike appearance. Through UV mapping, we can accurately map 2D textures onto the surface of a 3D model, making the model look vivid. This article will explain in detail how to use UV mapping correctly.

<h2>Understanding the Basic Concept of UV Mapping</h2>
The "U" and "V" in UV mapping represent the horizontal and vertical coordinates, respectively, similar to the X and Y axes in a 2D plane. Essentially, it is a way to unfold the surface of a 3D model into a 2D plane so that we can conveniently draw or add textures on this plane. Imagine taking a complex 3D object, like a human body model, and unfolding it into a plane just like peeling an orange. This plane is the basis for our UV mapping operations. Only by clearly understanding this basic concept can we better carry out the subsequent operations.
<h2>Preparing Appropriate Texture Materials</h2>
Before performing UV mapping, we need to prepare appropriate texture materials. These materials can be self-drawn or high-quality texture images collected from the Internet. The choice of texture should be determined according to the characteristics and requirements of the model. For example, if you are making a wooden furniture model, you need to select an image with the characteristics of wood texture; if you are making a metal object, you should pick a material with metallic luster and texture. Moreover, the resolution of the texture should also be appropriate. If it is too high, it may cause performance problems, and if it is too low, the surface of the model will look blurry.

<h2>UV Unfolding of the Model</h2>
This is a very crucial step in the UV mapping process. Different 3D modeling software has its own UV unfolding tools and methods. Generally speaking, we need to first select the part of the model to be UV unfolded, and then, through operations such as cutting and stitching provided by the software, unfold the surface of the 3D model into a 2D plane as reasonably as possible. During this process, we should pay attention to minimizing the stretching and distortion of the texture. Once stretching or distortion occurs, after applying the texture, the surface of the model will show unnatural deformations, affecting the final effect. This requires us to patiently adjust and optimize the UV layout to ensure that each part can be unfolded smoothly.
<h2>Mapping the Texture onto the UV Coordinates</h2>
After the UV unfolding of the model is completed, the next step is to map the prepared texture materials onto the UV coordinates. In the software there are usually corresponding mapping tools, and we can accurately attach the texture to the UV plane through simple operations. During this process, we should pay attention to whether the direction and position of the texture are correct and ensure that the texture can completely cover the area that needs to be textured, and the connection between each part should be natural and smooth. For example, for a model composed of multiple parts, we should ensure that the texture transition between different parts is natural, without obvious seams or misalignments.
<h2>Adjusting and Optimizing the UV Mapping Effect</h2>
After mapping the texture onto the UV coordinates, it doesn't mean that the UV mapping is completed. We still need to further adjust and optimize the mapping effect. This includes checking for problems such as texture stretching, distortion, and unnatural seams and promptly fixing them. We can improve the effect by adjusting the position and scale of the UV coordinates. At the same time, according to the actual needs of the model, we can also appropriately adjust the color, contrast, and brightness of the texture to make the appearance of the model more realistic and beautiful.
<h2>FAQ</h2>
My texture looks very blurry after being applied. What should I do?
First, check whether the resolution of the texture material itself is high enough. If it is too low, consider replacing it with a higher-resolution texture. Also, it could be a problem during the mapping process, such as the texture being overstretched. In this case, you need to readjust the UV unfolding and mapping operations to minimize the stretching of the texture.
How can I avoid texture stretching and distortion during UV unfolding?
A: When performing UV unfolding, you should reasonably choose the position of the cutting line, preferably along the places where the texture change on the model surface is not obvious. After unfolding, carefully observe the shape of each part and promptly adjust the areas that show signs of stretching or distortion by operations such as stitching and moving the UV coordinates to restore the normal shape.
The texture transition between different parts is unnatural. How can I solve this?
You can first make a unified plan for the UV layout of different parts before mapping the texture to ensure that their relative positions and sizes on the UV plane are appropriate so that the texture can be naturally connected when mapping. If the unnatural transition has already occurred, you can improve it by adjusting the position, scale ratio, etc. of the texture on the UV plane. You can also consider using some texture blending tools provided by the software to make the transition more natural.
To sum up, using UV mapping correctly requires us to have a deep understanding of its basic concept, carefully prepare texture materials, master the skills of UV unfolding of the model proficiently, accurately map the texture onto the UV coordinates, and continuously adjust and optimize the mapping effect. Only in this way can our 3D model be dressed in a perfect "texture outfit" and show a lifelike effect.
